ABSTRACT:
Several forms of latching mechanism are disclosed incorporating a pivotal cam and a spring-loaded plunger. In the preferred form, a lock pin is also included. The latching mechanism is particularly suited for latching interfitted members at least one of which is tubular. In one preferred form, the members are prevented from being interfitted by the lock pin which bars entry into the tubular member. The lock pin may be withdrawn only when the tubular member occupies a preselected orientation relative to a fixed frame member. When so oriented, the plunger's hose is received within a recess. This allows pivotal movement of the cam lever, and permits withdrawal of the lock pin. After the members have been interfitted, the lock pin is reinserted by pivotal movement of the cam lever. In its reinserted position, the lock pin enters aligned slots in the members, thereby locking the interfitted members together. Once the lock pin has been reinserted to lock the interfitted members together, the lock pin may not be withdrawn unless the members occupy a preselected orientation relative to the frame member.
